Abstract

The invention provides a third-rail lower pneumatic current collector. Technical problems of the traditional three-rail lower pneumatic current collector for a rail transit vehicle that a plurality of cylinders are used, a plurality of gas circuits are arranged, the operation is complicated, the cost is high and the like are mainly solved. The third-rail lower pneumatic current collector is characterized by comprising a mounting back plate assembly(1), a cylinder crank connecting rod assembly(2), a tension spring assembly (3), a left flexible bearing seat (4), a right flexible bearing seat (7), an insulated swinging arm (5), a current collecting slip shoe (6), an upper insulated protective cover (8), a lower insulated protective cover (9) and the like, wherein the left flexible bearing seat (4) and the right flexible bearing seat (7) are connected with the swinging arm; and the current collecting slip shoe (6) is mounted on the swinging arm (5). As only one cylinder is needed to be connected with a shoe derailing crank assembly, the third-rail lower pneumatic current collector provided by the invention, is simply and reliably structured and convenient to operate and maintain. The third-rail lower pneumatic current collector provided by the invention can be widely applied tovarious three-rail current collectors for the rail transit vehiclesor used for improving the original current collectors.

Description

technical field

[0001] The invention relates to a current collector, which is a pneumatic current collector for the lower part of the third rail used in rail transit vehicles. Background technique

[0002] At present, two or more cylinders are used to realize the pneumatic and manual shoe-off functions of the existing three-rail lower pneumatic current collector for rail transit vehicles. Many cylinders are used, the cost is high, the maintenance and repair are inconvenient, and the safety and reliability are poor. Contents of the invention

[0003] The purpose of the present invention is to solve the technical problem that the existing subway vehicle three-rail current collector needs to use multiple cylinders to realize pneumatic and manual boot removal or reset, so as to provide a pneumatic and manual boot removal with only one cylinder. Or reset function, installation, maintenance, easy to use, fewer failure points and reliable dynamic follow performance of the third ...
